About Greg Bronson CTS-D

In my role with AVIXA standards and content teams I provide technical advisement and strategic leadership. This primarily includes standards publications and the Exam Guide books. My interests span the broad spectrum of AV/IT technologies and systems our industry provides.  Prior to taking a staff role with AVIXA I worked supporting AV/IT solutions for both public and private education as a "Technology Manager" (roles including repair, installation, design and project management) as well as a longtime volunteer for AVIXA education and standards programs.

Sorry, I'm not up to date on sample questions - perhaps @Paul Streffon, CTS-D, CTS-I or @Greg Carstens

Hi Chad,

Using your test case variables (metric equivalents for distances) I get 13,243.  Yes, it's a big number (as is the 98 dB SPL at listener position).  From what I'm aware of, the 20 dB headroom for music (and 10 dB headroom for speech) recommendation goes back some time ... and have seen occasional debate(s) on justification thereof.  In my opinion the spirit is to minimize any potential of amplifier clipping/distortion - but just how much (headroom) also depends on the content/application so "mileage may vary".  Also noting loudspeaker sensitivity impact on result.

So true!  We (AV pros) have terms/meanings that vary across the many regions of the world but also within (for instance) allied trades that might not know what we're referencing.  Even worse (perhaps) are terms with more than one meaning depending on what aspect of AV is involved! 

Will take this as a chance to plug AVIXA Audiovisual Glossary of Terms   Let us know if you don't find a term (or disagree with a definition) as we plan to periodically update this in consultation with our volunteer SME's.

Very nice summary of some key subtopics to all important (and ongoing) AV network security.  For those interested in more on the topic see also Recommended Practices for Security in Networked Audiovisual Systems | AVIXA.

Thanks for Paul's deep dive posts (and Christopher for bringing topic up) ... just chiming in to also highlight that there was a correction to the EPR formula from CTS-D Exam Guide, Second Edition.  You can find that at following https://xchange.avixa.org/manage/posts/196069

Hello Sheldon - AVIXA doesn't have any standard that covers this situation.  Seems pretty unique but perhaps others in this forum have encountered similar and might comment?

Hi Christopher - interesting question.  Per CTS-D Exam Guide 2nd Edition starting ~page 145, it's an approximation of speaker spacing (creating overlap) delta of the distance (not area) between two speakers from otherwise "edge to edge" coverage distance.
